When the Immortal Emperor returns to the dust, he becomes angry because of his beauty; he is invincible in the overall situation and protects his family.
He was a cultivator who traveled through time and space. He once stood at the top of the world, but he became the fourth son of Emperor Yongle of the Ming Dynasty - Zhu Gaojie.
In this Dharma-ending era when mortals are extinct, his return to the path of immortality has become the only myth in the world. Imperial power, wealth and honor were nothing but a passing thought in his eyes. He originally thought that he would only pursue Taoism and freedom in this life, until the Jingnan troops rose up, and his childhood sweetheart Su Lianxue was abducted by Emperor Jianwen, and her life and death were unknown.
In anger, he once wanted to wash away the mountains and rivers with blood, but in order to fulfill his father Zhu Di's imperial path, he suppressed the hatred of Fentian and walked away alone. For more than ten years, he traveled all over the nine states, pointing his sword at the remnants. He was the "White Shura" who made the lonely officials of the old dynasty fearful. He killed decisively because of a promise: "The lives of Jianwen's remnants are mine."
Under the prosperous age of Yongle, undercurrents surged. The prince is benevolent, the king of Han is arrogant, and the king of Zhao is evil. The battle for the throne is becoming increasingly intense. The nephew Zhu Zhanji who needed his protection back then has grown into a heroic grandson, but he has a deep love for Jianwen's orphaned woman, step by step into a dangerous chess game.
When Zhu Gaojie felt something in his heart and returned to Beijing, what awaited him was not only his aging and thoughtful father, his brothers with their own thoughts, but also a huge whirlpool related to the fate of the empire. When he discovers that the close relative he protects with all his heart is entangled with the enemy he vowed to kill, how will the immortal sword fall?
He is the only immortal in the Ming Dynasty and the strongest sword of the Zhu family. This time, he wants to find his true love, cut off his grudges, and become invincible in this mortal world to fight for the estranged man.
